What we are doing
From 1 September to 22 September, we will be building cross passage 14 near Conway Crescent, Perivale. We’re building cross passages between the railways tunnels to allow HS2 passengers to get to a place of safety in an emergency. They are about every 500 meters on the tunnels route.
To build the cross passage, we will break into the side of the completed tunnel. This might cause some noise and vibration, which may be heard or felt as ground borne noise in nearby buildings. We’ll work 24 hours, seven days a week. To avoid overnight disturbance, we’ll limit noisy activities to between 7am to 10pm Monday to Sunday and carry out quieter works at night.
Cross passage 14 is about 26 metres below ground and lies within a thick layer of London clay, which will reduce noise and vibration during these works.
